CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 467,882, dated January 26, 1892.

Application filed October 26, 1891.

Serial No. 409,774. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANK AVERILL Fox, of San Francisco, county of San Francisco, and State of California, have invented a certain new and useful Improvement in Car- Couplers, of which the following is a specification.

This invention relates to that class of carcouplers in which there are two automati- IO cally-interlocking sections having means for securing them as interlocked; and it consists in the construction and novel arrangement of parts, as hereinafter set forth.

I will describe a car-coupler embodying my improvement, and then point out the novel features in claims.

In the accompanying drawings, Figure 1 is a top or plan View of a coupler embodying my invention with a swinging section in an open position. Fig. 2 is a top or plan View thereof with the swinging section in a closed or locked position. Fig. 3 is a rear end view. Fig. 4 shows a swinging section, partly in vertical section, on the line 4 4 of Fig. 1. Fig. 5 is a top or plan view of the swinging section. Fig. 6 is a section through the line 6 6 of Fig. 2, looking in the direction indicated by the arrow. Fig. 7 is a section through the line 7 7 of Fig. 1, with a portion broken away and drawn on a reduced scale. Fig. 8 is a section, on a reduced scale, on the line 8 8 of Fig. 5. Fig. 9 is a section similar to Fig. 4, but showinga slight modification.

Referring by letter to the drawings, A designates a fixed section or coupler-head adapted to be secured to a car in the usual manner. This section A has the usual guide-horn a at one side, and at the opposite side has forwardly-projecting lugs A, forming bearings 4o for a horizontally-swinging interlocking section A". The section A has a reduced portion or block A, adapted to engage between the lugs A, and both the lugs and the block A are vertically perforated for the passage of a hinge-pin a. It will be seen by this construction that a hinge-joint is formed between the sections A A of the coupling and that the block A forms one member of the joint and the lugs A form the other member of the joint. The outer ends of the lugs A are rounded transversely, and each lug has a vertical wall or bearing-surface a and an inwardlyinclined wall or bearing surface a The section A has a transversely-curved vertical bearing-wall a, conforming to the wall a and a transversely-curved inclined wall or bearing a, conforming to the wall or bearing a By this construction I provide an increased thickness of metal at the junction of the main portion of the section A and the block A*. This is advisable, because in ordinary couplings of this character a break is most likely to occur at this point when two couplings come in sudden and violent contact. Also, as the lines of the walls a a a a are vertically in straight lines, they are easily fitted one with another, and in casting the patterns are more easily drawn. The interlocking section A has a projection 13 at substantially right angles to its face. The projection B has a transverse shoulder or abutment b 011 its upper side adapted to impinge against a shoulder 1), extending downward from the upper wall of a chamber C within the section A. IVhen the section A is in its closed or locked position, it will be seen that the engaging shoulders I) b relieve the pin a. of considerable strain, and, indeed, if the pin a were removed the shoulders would hold the parts firmly together.

The projection 13 carries a locking-bolt D. This bolt D is movable longitudinally and vertically within a recess cl in the projection B and is automatic in its locking motion. The bolt has a swinging motion within the recess, 8 5 and as a means for this swinging motion I have shown the bolt in Fig. 4 as suspended by two links (1, the upper ends of which are pivotally connected to the upper wall of the recess d and their lower ends pivotally cono nected to the bolt D. As one link d is connected to the boltnear its center and the other link connected to the bolt near its inner end, it is obvious that the bolt will automatically swing outward into a recess or keeper 0 in 5 the section A, and the two links will maintain the bolt parallel at all times with the walls of the recess d.

In Fig. 9 I have shown the bolt D as suspended within the recess (1 by means of a sin- [00 gle link d In this example as a means to cause the bolt to maintain its parallelism relatively to the walls of the recess (1 I provide the lower portion of the rear wall of the recess with anincline d upon which the lower inner edge of the bolt slides. By suspending the bolts on links, as described, they operate easily and with very little friction.

E designates a lever for moving the bolt D out of the recess 0 when it is desired to unlock the section A This lever is fulcrunled to lugs 8, extending laterally from the section A, and has its inner end projected through a hole in the side of the section A into the path of the bolt D. By moving the outer end of the lever E outward the bolt will be forced into the recess d, allowing the section A to be moved to an open position.

Having described my invention, what I claim is 1. In a car-coupler, the combination, with a fixed section having the forwardly-extending lugs provided with the transversely-curved bearing-walls having the vertical surface and the inclined surface, of the swinging section provided with the transversely-curved bearingwalls having the vertical surface and the inclined surfaces, all of said bearing-surfaces being in straightlines upward and downward, substantially as specified.

2. In a car-coupler, the combination, with the fixed section and the swinging section, of the longitudinally and vertically swinging locking-bolt carried by said swinging section, substantially as specified.

3. In a car-coupler, the combination, with the fixed section and the swinging section,of the locking-bolt, a link or links connecting said bolt to the swinging section within a recess thereof, and a lever for moving said bolt in one direction, substantially as specified;

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANK AVERILL FOX.
